To'allwhom it may-'concerm Be aknown vthat I, HENRY Aeon-, a can i'zenof'the United States, residing at yEmporiun1,.county of Cameron; andStateof Penny Sylvania?, have invented certain new and useful4 I'mrovements `in Machines for Forming ay Qartri e-Ro e fromExplosiveeGrelatin,"'ofl Whichv t efo'l owing-is a s'peclication.

' w Thisv invention :relates to machines 'for' '10'forming'acartridgerope fronti,explosivev gelal under pressure, thnogh'anozzle from which the gelatin emerges as ajcontinuous r6 4e, thell`diameter of which maybefrom le'sst an an y inch to upwards of twoinches, this rope 'being he manufactureof cartridges -fr'o'm eX- plosivegelatin, which is a plastic substance of'a consistency depending `'uponvarious conf. ditions,' is generally carriedon by forcing it,

cutinto suitable,l lengths, usuall about eight inches, afteremergencejfrom t enozzle, -to thereb form the cartridges Whichare' thensuitab y Wrapped so `as to ready-for'- coini mereial use.

Machines of the characterf set forth have usually employed a horizontal'screw-1 'termed by skilled Workers `in explosivesa paeking screw?, forforcing the explosive gelatinv -through :the nozzle,and associated 'withthis acking ls crewrneans' have been employed to eed the plastic gelatintothe screw.'

Detachably bolted to the vtop of the pack-l 'lng screw case 61 by bolts63, is a conical' hopper 22, Whose upper part.23 is in the forrnof acylindrical ring, which is detach? ably connected to the lower partthereof by the flanges and bolts 24, permitting removal of the upperpart for purposes of cleaning.
